Abstract: A multiple access satellite communication system in which a plurality of mini-earth stations each transmits data packets to a hub earth station via a satellite over an inbound channel, while the hub station transmits to the mini-earth stations in a broadcast mode over outbound channels. Each mini-earth station selectively uses a fixed assignement access method, random access method, and demand assignment access method, depending on the frequency of the transmission from a terminal connected thereto, the amount of transmitted data, and whether or not the transmission from the terminal is periodic. The hub station outputs a reception response signal to the outbound channels by determining whether or not a conflict of data packets or a transmission error has occurred on the inbound channels. Packets for re-transmission are sent out to the inbound channels by the demand assignment access method at all times, with no regard to the access method used at the time of transmission.

Abstract: An apparatus and method for loading BIOS from a diskette drive (66) into a personal computer system (10) normally connected to a fixed disk drive (62). The personal computer system (10) further includes a system processor (26), a random access main memory, a read only memory (36) and a switching means. The switching means generates a signal to indicate a mode for whether BIOS loads from either diskette or disk. In a priority mode, BIOS loads immediately from diskette. In a recovery mode, BIOS loads from diskette after testing the disk subsystem. The read only memory (36) includes a first portion of BIOS and data representing the type of system processor (26) and system planar (24) I/O configuration. The first portion of BIOS initializes the system (10) and queries the switching means. If the fixed disk is not available or the master boot record on the disk is invalid, the first portion of BIOS reads in a master boot record from the diskette drive (66). For either mode, the master boot record includes a data segment (122-138) and an executable code segment (120). The data segment (122-138) includes data representing system hardware and a system configuration which is supported by the master boot record. The first BIOS portion transfers control to the executable code segment (120) which confirms the master boot record is compatible with the system hardware by verifying that the data from the data segment (122-138) of the master boot record agrees with the system processor (26), system planar (24), and planar I/O configuration. If the master boot record is compatible with the system hardware, the executable code segment (120) confirms that the system configuration has not changed and loads in the remaining BIOS portion from the diskette drive (66) into random access memory (32). The executable code segment (120) then verifies the authenticity of the remaining BIOS portion and vectors the system processor (26) to begin executing the BIOS now in random access memory (32). BIOS, executing in random access memory (32), then boots up the operating system to begin operation of the personal computer system (10).

Abstract: An electrophotographic machine with a transfer corona generator (13) for producing ionic flow to the backside of print paper to electrostatically attach the paper to the photoreceptive image bearing surface (12). The machine includes a flexible support member (40-44) which is movably mounted to mechanically press the print paper against the photoreceptive surface within the transfer zone, preferably at or near the region of peak transfer charge distribution. In that manner, charge from the transfer corona attaches the print paper to the photoreceptive surface at the line of release from the mechanical pressure applied by the flexible support member and thereby eliminates voids in the transfer of toner to print paper caused by air gaps between the paper and the photoreceptive surface.

Abstract: Apparatus and method for performing an application-defined operation on data as part of a system-defined operation on the data. The apparatus and method are embodied in a distributed transaction processing system in which processes running on component systems which may be heterogeneous interact according to the client-server model. In the apparatus and method, a type is associated with the data and application-defined operations which are part of certain system-defined operations are defined for each type. The system-defined operations which the application-defined operations are part of include allocation, reallocation, and deallocation of buffers and sending buffers between clients and servers using remote procedure calls. In the allocation and reallocation operations, the application-defined operation is initialization; in the deallocation operation, it is uninitialization. In buffer sending, the application-defined operations include operations done on the buffer contents before sending, routing, encoding the buffer contents into a transfer syntax, operations done on the buffer contents after sending, decoding the buffer contents from the transfer syntax after receiving, and operations done on the buffer contents after receiving. Data structures in the processes associate the data and its type and a type and its application-defined operations. Servers employ a shared bulletin board data structure to indicate the types they accept.
